EUGENE sum, or BUFFALO, new YORK.

j sass Loci;

To all whom it may concern:

Be it known that I, EUGENE GUsY, a citizen of the United States, residing in Bufialo, in the county of Erie and State of New York, have invented new and useful Improvements in Sash Locks,-of which the following is a specification. 1

Thisinvention relates to a sash lock which is more particularly designed for-use in connection with a window having upper and lower sashes which are capable of sliding vertically and also swinging laterally with reference to each other in the window frame for the purpose of either opening or closing the sashes for ventilation as well as permitting the sashes to be reversed so that either side of their glass panes may be washed or cleaned from the inner side of the room.

It is the purpose of this invention to provide a sash lock for windows of this character which will permit of either sliding these sashes vertically relatively to one another or swinging laterally relatively to one another to a limited extent, so as to permit of ventilating the room and still prevent unlawful intrusion into the building from the exterior, said locking device being so organized that the'same may be rendered inoperative and permit the sashes to slide vertically relatively to each other to the fullest extent and also to completely reverse the sashes when this is required. I

In' the accompanying drawings:

Figure 1 is a fragmentary perspective view of a window showing my improved sash'lock applied to adjacent parts'of the upper and lower sashes which latter are capable of both a sliding and a pivotal motion within the window frame. Figure 2 is a fragmentary vertical section, on an enlarged scale, of the opposing portions of two window sashes, equipped with my improved sash lock, this section being taken on line 2-2, F ig. 4. Figure 3 is a fragmentary vertical section, on an enlarged scale, taken on line 3'3, Fig. 2. Figure 4 is a fragmentary horizontal section taken on line a e, Fig. 2. Figures 5, 6 and 7 are detached perspective views of the main parts of my improved sash lock. v

Similar characters of reference. refer to like parts throughout the several views.

7 Specification of Letters Patent. Pggfinted Aug. 8 1922 Application filed July 7, 1920. Serial No. 394,516.

Although my improved sash lock is applicable to windows which may be variously constructed, it is more particularly designed for a window having one or more sashes 3 which are capable of both a sliding and a pivotal motion within the frame. particular instance shown in the drawings, the window to which my improved sash look In the is appliechcomprises a frame 10 which is provided on the inner side of each ofits uprights or stiles 11 with two vertical runways 12, 13. In these runways are slidably mounted hangingbars 14, 15 each of which ismovable vertically and preferably though not necessarily constructed of sheet metal. Within the frame are arranged the upper and lower sashes l6, 1?, which'are adapted'to slide vertically past each other and'also are capable of turning about horizontal axes, this being accomplished by pivotally connecting each stile or upright bar of the upper sash about midway of its height with the central part of the hanging bar 14 in theouter runway by means of a horizontal pivot screw or pin 18- while each upright stile or bar of the lower sash is pivotally connected about midway of its height with the central part of an inner hanging bar 15 by means of a horizontal pivot pin or screw 19, as shown in Figs. 1 and 4. By this construction both the upper and lower sashes may be raised and lowered within the frame in the usual manner for ventilating or-other purposes, and these sashes may also be rotated on their horizontal pivots for the purpose of reversing them, so that either side of the glass panes of the sashes can be cleaned from the inside of the building.

My improved sash-lock which is associated with the upper and lower sashes of a window thus constructed, preferably comprises a horizontal guide tubeQO which is secured transversely to the upper edge of the lower sash adjacent to one corner thereof by providing opposite sides of this tube with laterally projecting flanges 21 which receive fastening sorews'22. On its upper side this guide-tube is provided with a longitudinal slot 28 which preferably extends the full length thereof. 7

On the adjacentlower part of the upper sash, preferably the lower end of one of its upright stiles, is mounted a vertical longitudinal guideway 24: which is provided with an undercut slot 25 preferably of T-shaped form in cross section, thislongitudinal guide" being preferably secured to the upper sash by means of screws 26 passing through the" the locking rod is provided with a longitudinal, feather 30 but the periphery of its frontor outer part is made substantially cylindrical. ,The coupling head on the lock-' ing rod is engaged with the T-slot of the vertical :guideway by passing this head through the narrow part ,of the slot--25 while the long side of the head is parallel with this slot, andafter this head has passed into the wide part of this slot the head is turned so that the same extends across the narrow part of the slot, thereby coupling the vertical guideway and the upper sash tothe lockingrod and lower sash. When theupper and lower sashes are thus'connected, one or the other of the samemay bewmoved vertically relatively tothe other vto a limited extent by reason of the fact that the coupling head at this time moves vertically in the T-shaped slot of the vertical guide way. The length .ofv this slot is only sufficient to permit of opening either of the sashes slightly at thetop or the bottom I of the frame as well as to permit both of ifguideway. The rangeof movement of the,

the same'to be shifted .for producing a slight opening at, the top, and the .bottom of the frame. The length of this movement is however so determined that unauthorizedpersons attempting to gain an entrance through such openings will find the-same inadequate for the passage of their hands or instruments which may be employed in an attempt to break into the house. NVhen. swinging either one of the sashes laterally with reference to theqother, the docking rod will be drawn outwardly or forwardly in the horizontal guideway but,

the extent of this movementis limited by engagement of the stop or handle 29 engaging with the inner end of the horizontal opposing meeting edges of the upper and lower sashes is preferably so determined that only a comparatively narrow passage hands of a "of tools w ich' might be employed for naeaeoo way is formed between the meeting portions of the sashes for ventilating purposes, but not sufficient to permit the passage of the ossible intruder or the passage burglarizing a house. \Vhile the two sashes 'engage their meeting portions, as shown in Figs, 1, 2 and 4;, the feather 30 of the locking rod is arranged wholly outside and in rear-of; the horizontal guideway, so that at this time the attendant in the building or room is capable of freely turn-- ing the locking rod and couple or uncouple the two sashes for the purpose of rendering the same proof against unlawful intru sion from the outside, or to permit of fully opening the sashes either by avertically sliding or a rotary motion of the same relatively to each other. But when the sashes are turned relatively to each other, so as to separate their meeting portions one from the other, then the feather 30- of the locking rod enters the slot 23 in the horizontal guideway, thereby vpreventing the locking rod from being turned and uncoupled fromthe upper sash if an attempt to do so should be made by a person using a pair of nippers and gripping the outer part of the locking rod which is exposed between the meeting portions of the upper andlower sashes. It will thus; be apparent that so long as the meeting portions of the upper and lower sashes engage with each other, it is possible for the attendant to freely couple and uncouple these sashes, but when these sashes are swung into a more or less open position relatively. to each other then the locking rod cannot be turned, especially not from the outer side ofthe building,-so that by this means tampering with this look is frustrated. p

This sash lock consists of comparatively few parts which can be producedat low cost, the same can be readily installed, on the sashes of windows as now generally constructed, and when in use the same does not detract from the neat and finished appearance of the'window. i

I claim as my invention: 7

A sash lock for connecting twoysash the inner part of the periphery of said rod being provided with a longitudinal feather adapted to engage the slot in said horizontal guide-Way while the outer part of said periphery is cylindrical, said head sliding vertically in said T-shaped slot upon raising or lowering'either of said sash members, and said feather being adapted to engage the slot of said horizontal guide tube upon moving either of said sash members laterally relatively to the other, and said stop being adapted to limit such lateral movement.
